That was quick. I sent an email to the australian company (tempe tyres) and their turnaround time is only about 2 weeks. Pricing for 17 x 8's is $800 each. Pricing for 17 x 10's is $860. Both prices are delivered to USA - presumably texas since that's where i'm located.
I have asked if pricing was US$ or AUS$, but I don't think there's much of a difference any more. **Edit - prices are in AUS$ ** I'll suggest to them that they hook up with some wheel distributors in the US as these are highly sought after in the TB community.
Feel free to shoot them an e-mail. I just went to their website and hit the "contact us" button. They were back to me reasonably quickly considering a 12-hour time difference. I'll post findings in the brakes, wheels, suspensuon forum also for future reference.
